Oysters from Murotsu Bay vs Oysters from Hyogo Prefecture in General – KODAWARI Staff Taste Test

Hi all, since you are reading this, you must be wondering what’s the difference between KODAWARI’s oysters from Hyogo Prefecture and Murotsu Bay. We are fortunate enough to be able to try out both, so let’s just cut through the chase, here is our verdict on the difference between the both of them.

TLDR: Hyogo Prefecture is famous for its oysters in general, but according to the locals, the ones from Murotsu Bay are the cream of the crop. Murotsu Bay is also a part of Hyogo Prefecture, however their geographical landscape is more suitable for oysters farming as the bay is being sandwiched between Ibo River and Chikusa River, causing the bay to be very rich in phytoplankton, the food source for oysters.

M Size Oysters from Hyogo Prefecture vs. L Size Oysters from Murotsu Bay

Packaging and Size difference

The ones from Hyogo Prefecture are M size, and come in packs of 10, while the ones from Murotsu Bay are L size, and come in 6 pieces per pack. We have a customer who asked us before if there is a possibility to have extra pieces per bag, and the answer is highly impossible. There might be a 1% chance for the M size Hyogo Oysters to have 1 extra piece, as these came in loose (a big box) from Japan, and our food processing team repacks them to packs of 10. However, there is 0.001% chance for the L size Murotsu Bay Oysters to have extra pieces in their bag, because they were processed and pre-packed in Murotsu Bay, Japan, before being shipped over to Singapore. As our product titles (and supplier) mentioned, the M size oyster shells from Hyogo prefecture has a size of averagely 8-10cm, while the L size ones we have from Murotsu Bay has the size of averagely 9-11cm. The shapes are also slightly different, as we realized that the M size oyster has a longer shape, while the L size oysters are slightly rounder. Both sizes are already pre-cleaned and processed in Japan, so all we did is just thaw, shuck and slurp.

Taste Test


Both oysters are equally good, to be honest, however, the L size oysters from Murotsu Bay have a milkier texture. It also has a more satisfying ‘slurp’ as compared to the M size oysters from Hyogo Prefecture, and since it is also slightly bigger, it is like you just slurp in a mouthful of sea breeze. According to our friends who tried them, they said that the ones from Murotsu Bay give them a more eating-by-the-sea vibe as compared to the M size oysters. The M size oysters have a slightly firmer texture if compared with the other ones.

*We pair them with some lemons, best combo ever 😀


We also tried grilling both oysters, and we were torn by the options. Both are equally good; however, the M size oysters have a better meat juice ratio than the L size oysters. We grilled them for 7 minutes, and the L size oysters are still quite plump, so if you prefer to taste the meatiness of oysters, do get the M size ones. But if you prefer briny, juicy, and plump oysters when you grill them, do go with the L size oysters (Although our Japanese boss said that it is such a waste to grill these, as they are best eaten as sashimi oysters).

Staff’s Recommendation

If you are a first-time oyster eater and are afraid that they are too briny for you, you can opt for the M size oysters from Hyogo Prefecture, which have a milder taste as compared to the L size ones from Murotsu Bay. It is also a better option if you are looking to grill them, as they have more of a firm texture after grilling.

If you are already an oyster connoisseur and want to have some great oysters for dinners or gatherings, get the L size oysters from Murotsu Bay, because we’ve tried more than 1 packet now, and they do not disappoint.

Some FAQs for Oysters

Question: Do I need a shucking knife to shuck oysters in general?

No, speaking from experience, many of us usually just use a butter knife to shuck these oysters. However, you do need to make sure that you thaw the oysters long enough to use a butter knife to shuck. If you did not thaw for long enough, there might be a possibility that the shell might be too brittle to shuck due to the freezer temperature, and you might end up accidentally stabbing the oyster meat in during the process.

Of course, using a shucking knife is always better, but if you do not want to buy one, a butter knife/small blunt knife is good enough. However, do be careful so that you don’t hurt yourself 😀

Question: How long should I thaw my oysters?

The safest way to thaw your oysters without compromising the texture and quality is to soak them in a bowl of 50℃ water for 4-5 minutes. But if you do not have a thermometer to measure the water temperature, running them under tap water for 3-4 minutes is good enough. If you are still unable to shuck them, just run them in tap water for 20-30 seconds longer.

Question: Do I have to eat my oysters within 2 days from the purchase?

People often think that household freezers are unable to retain the oyster quality, however, that is not true. As long as you do not thaw it and refreeze, otherwise, all the oysters available on KODAWARI can last in your freezer for 2-4 months. As all the oysters were properly frozen during production, do rest assure that they are still safe to consume even though they are not kept under -18℃. As long as you keep them in your freezer, you can get a taste of Japan sea any time, any day you want 😀 The only thing you need to take note of is that you might not have enough fridge space for other stuff if you buy too much of oysters 😊

We hope that this taste test review gives you a rough idea of the differences between both of the oysters available on KODAWARI, and have fun eating them!
